connect to local area network through PPTP VPN (Synology DSM)

Credit goes to this forum post by vibrationbaby

In short, assign PPTP managed IPs into the same pool of local private network.

login as root through SSH.
go to /usr/syno/etc/packages/VPNCenter/pptp
edit the two lines for localip and remoteip pptp.conf. (@vibrationbaby provided the setting below. i used .200 and .201-205 while my DHCP managed 100-199. just choose some addresses that is not overlapping with existing DHCP pool.)
```
localip 192.168.1.210
remoteip 192.168.1.211-220
```
then it should work after restart the VPN Server through DSM web interface.

add Dynu.com to DDNS list on Synology NAS

(install ipkg to install nano follow the instructions here if necessary)
(Note: on my DSM 5.2, PATH setting in /root/.profile need to be commented out)
add below codes to /etc.defaults/ddns_provider.conf

[Dynu.com] 
        modulepath=DynDNS 
        queryurl=api.dynu.com/nic/update?hostname=__HOSTNAME__&username=__USERNAME__&myip=__MYIP__&password=__PASSWORD__

1. Use [Edit HTML] in "Template" to add following line into the header.
<script src="https://google-code-prettify.googlecode.com/svn/loader/run_prettify.js"></script> 2. Then, go "Template", [Customize], [Advanced], [Add CSS] to paste following codes, and click [Apply to Blog]

  padding: 10px 10px 10px 21px;

As the result, codes will be prettified by the script when encapsulated by
<pre class="prettyprint"> def example: codes = here </pre> In some cases: <xmp class="prettyprint"> <some codes="" with=""> <html like="" tags=""> </html></some> <|xmp> (Note the slash need to be changed. It was replaced by vertical bar here for displaying purpose. For more detail, see this)

install python pip on linux without root

While trying to run python on Karst, i was (not) surprised that the new server does not come with numpy/pandas, but again amazed by that having no pip available.
